Who would have thought that in The Great Baby Boom of 2012 it would be the reality stars who are the ones quietly giving birth without making a huge spectacle out of it? We’re only just now meeting Kourtney Kardashian‘s daughter Penelope Disick; and just now Kristin Cavallari tweeted about her son’s birth but didn’t have the decency to include a twitpic of the baby with dad Jay Cutler. Really, I expected more from someone who aired all her drama on Laguna Beach and The Hills! Here’s the tweet, if you’re into boring stuff like that:

We are thrilled to welcome Camden Jack Cutler into the world. He was born this morning weighing 7lbs 9oz. Everyone is doing great!

I’m just teasing: Glad to hear that all went well and there’s another celebrity baby safely delivered. And maybe this low-key announcement is Kristin turning over a new leaf as a mommy: Staying out of the spotlight somewhat, acknowledging the birth without looking for attention like a non-famous person would, and hopefully not already calculating the pay for an InTouch cover story.

Of course, we won’t know for sure til she starts to lose the baby weight. If she takes a normal amount of time, she might have put the reality career behind her. But if we see more photos of her holding her gym bag than her newborn son, we could be seeing more of this Kristin:
